MIDI System Exclusive Messages
The Particle uses MIDI System Exclusive Messages to get and set configuration properties and state.
The protocol is very similar to MIDI Capability Inquiry (MIDI-CI) Property Exchange, but the defined prop-
erties and semantics for MIDI-CI Property Exchange are not part of the MIDI-CI specification and have not
been published as of March 2019.
The following System Exclusive messages can be used to configure the particle, read current configura-
tion, and access other functionality that is not available through standard MIDI messages (for example,
saving presets to internal memory). You can use these messages to write a custom editor or configure
a MIDI controller to control the Particle. Our web editor prints the System Exclusive messages that it
sends to the JavaScript console, so you can perform an action using the web editor and then copy the
SysEx to your controller.
The basic format is the same for all messages:
